NEED: This is often thought of as a physiological or biological requirement for maintaining life, such as the need for air, water, food, shelter, and sleep. Satisfaction is achieved by fulfilling needs. Physiological needs should be contrasted with psychological wants that make life more enjoyable but are not necessary to stay alive. However, when push comes to shove, and the nitty gets down to the gritty, it matters very little to markets if people need goods or want goods, so long as they are motivated to satisfy them. This motivation is what drives economic activity.

AD CURVE: The aggregate demand curve, which is a graphical representation of the relation between aggregate expenditures on real production and the price level, holding all ceteris paribus aggregate demand determinants constant. The aggregate demand, or AD, curve is one side of the graphical presentation of the aggregate market. The other side is occupied by the aggregate supply curve (which is actually two curves, the long-run aggregate supply curve and the short-run aggregate supply curve). The negative slope of the aggregate demand curve captures the inverse relation between aggregate expenditures on real production and the price level. This negative slope is attributable to the interest-rate effect, real-balance effect, and net-export effect.

RECOVERY The early phase of a business-cycle expansion that occurs shortly after a contraction has ended. During a recovery, the unemployment rate remains relatively high, but is beginning to fall, and real gross domestic product begins to increase, usually rapidly. However, because the contraction remains fresh in the minds of many, it may not be immediately clear that the trough of the contraction has actually ended.
